Increased fetal hiccups at end of pregnancy?

Reaching out to see if anyone else experienced feeling their baby hiccup more at the end of their pregnancy? Currently 38 weeks and I feel like suddenly I notice more rhythmic movement that feels like hiccups. Everything I read online says that hiccups should decrease as I get closer to labor :/ and I’m concerned on how to know if their hiccups or seizures. I have a doctors appointment in two days and plan on bringing it up then but any advice helps.
